S-LFD Fire and Gas-Fire Damper SOLAS A0-A60

The MED certified S-LFD fire damper, equipped with a thermal fuse, is designed to prevent the spread of flames within the ventilation and air conditioning system for Marine and Oil&Gas installations. The 4-piece welded frame allows installation in load-bearing structures such as decks and bulkheads. Due to its construction, the S-LFD fire damper is particularly suitable for installation on yachts, leisure ships, cruise ships, commercial vessels, HVAC systems and offshore and onshore oil and gas installations.
S-LFD series can perfectly replace the phased out SFD/SFDT models.
